Abstract

Mirror objective comprising two reflecting surfaces (2, 3), a primary mirror and a secondary mirror, respectively, arranged in connection to a lens (1). The primary mirror and the secondary mirror together with the lens are arranged to form an excentric radiation path through the mirror objective. The optical axis of the mirror objective follows an N-shaped path through the objective and central diaphragming is avoided. The object and consequently the image are situated outside the geometrical axis of the mirror objective. The mirror objective shows a short distance between the object and the image and is, for example, suitable for reading bar symbols, letters and digits, and for reading optical discs or similar storage means. The invention also relates to an optical arrangement comprising two mirror objectives as described above, one of the mirror objectives being used for illuminating, the other mirror objective being used for imaging.
